IMPROVEMENT I N PUMPS.

The Schedule referred to in these Letters Patent and making part ofthelame.

To all whom it may concern v Be it known that I, ZARA.T. SWEET, ofTiskilwa, in the county of Bureau and in the State of Illinois, haveinvented certain new and useful Improvements in Railroad andStock-Pumps; and do hereby declare that the following is a full, clear,and exact description thereof; reference being bad to the accompanyingdrawingand to the letters of reference marked thereon making a part ofthis specification.

The nature of my invention consists in the construction and arrangementof a railroad and stockpump, as will be hereinafterfully set forth;

In order to enable others skilled in the art to which myinvention'appertains to make and use the same, I will now proceed todes'clibe its construction and operation, referring to the annexeddrawing, in which-- Figure 1 is'a side view of my pump, the cylinderbeing in vertical section.

Figure-2 is a section of the same.

-- A A represents the pump-cylinder, provided with a convex bottom, B,in the center of which is a ballvalve, a; r

Above and around this valve are guides 11 b, to'pre vent'the same fromrising too far and getting out of place.

The upper end of the cylinder A is conical-shaped,

and-from its apex leads a pipe, D, upward, as shown.

. Inside-of the cylinder A is placed the plunger or piston G,- which isalso provided with a ball-valve, a-',

and guids b for the same.

The plunger-rod E extends up through the pipe D,

and when the pump is in operation the water is drawn up around said rodthrough the pipe, and may be made to flow into a reservoir, trough, orany other suitable receptacle;

On the rod E, above the upper end of the pipe D, is placed a loosecollar or ring, d, which may be adj usted at any height by means of nuts0 0, one above and one below, this portion of the rod being providedwith screw-threads for that purpose.

Above the upper nut 0, around the rod, is placed a spiral spring, f, theupper end of which bears against that portion of the frame-work throughwhich the rod passes, and which acts as a guide for'the plunger-rod. Theaction of this/spring f is to throw the plunger or piston 0 down afterit has been raised.

The cylinder A is placed in the bottom of a well,

and the pump may be operated by hand or by the foot,

or by a train of cars passing, or by cattle or other stock, as will bepresently described.

To the collar d is attached a lever, G, which is suspended or pivoted inthe frame-work above the pump, the other end of said lever being, by achain, y, connected with a grooved wheel, H, on a shaft, h. On thisshaft is a cam, I, placed at the side of a railroad track.

Onthe side of the cars there is attached a bar, 7: with afriction-roller, i, which strikes the, cam I and turns the shaft 11..This, operating through the lever G raises the pump-plunger, carryingwith it a' quan tity of water. In this manner one train may be made topump up the water necessary for the next train.

When it is desired to l 1ave the pump operated by the cattle coming todrinkat troughs or other convenient receptacle placed at the mouth ofthe well, I propose to have an inclosure around the same. In the openingor passage to said inclosure is a hinged platform, J, connected bychains or rods-g'with another lever, G, which is also connected with thecollar d. The cattle or any other stock passing over the platform Jwill' thus pump up water for themselves.

The pump may also be operated or worked by hand, or by a foot-lever, ifso desired.

The levers employed may be either straight-0r elbow- I levers, orseveral combined. I do not confine myself to any particular shape orform ofthe same.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

l. The arrangement of the shaft 71 cam I, wheel H, chain g, and lever G,substantially'as shown and described, for operating a pumpby a passingtrain of cars, substantially as herein set forth.

2. In combination with the shaft h, cam I, wheel H,- chain 9, and leverG, plunger E, pipe D, and cylinder A with its valves, all constructed tooperate substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of October, 1870.

ZARA T. SWEET.
